Specification of Letters Patent.

Application filed June 15, 1915; Serial No. 34,273.

To all whom it may concern:

Be it known that I, CARL A. Benson, of 13 Itoscherstrasse, Leipzig-Gohlis, in the Kingdom of Saxony, German Empire, civil engineer, have invented certain new and useful Improvements in Boarding-Machines, of which the following is a specification.

My invention relates to boarding machines and more especially to machines of the kind where the folded-up hide is rolled to and fro between two plates at the fold. The object of my invention is to provide a boarding plate for machines of this class which will adapt itself easily to the differences in thickness of each hide and which will nevertheless avoid the drawbacks presented by former machines designed to accomplish the same results. 7

In the machines hitherto in use the board ing plates, in order to allow them to adapt themselves to the differences in the thickness of different parts of a hide, were composed of a number of smaller plates, rigid in themselves but movable relatively to each other, each plate being supported by an elastic support such as a spring or the like and liable to recede or to assume an oblique position. This arrangement however has proved to give bad results on account of the joints between the single plates producing stripes or furrows in the hide to be boarded, thus rendering it inferior in quality.

In the boarding machine according to my invention these drawbacks are avoided by employing boarding plates presenting a continuous working surface although fully adapting themselves to the inequalities of the hides. In order to obtain this result the boarding plate is composed of two parts, viz. the working plate proper consisting of a rather soft and very elastic material such as cork, and a supporting plate of an equally elastic but more rigid material such as thin wood, steel or the like. The two plates are supported in their turn by a number of springs juxtaposed at certain distances all along the bottom surface of the supporting plate, said springs being adapted to be adjusted according to the varying average thickness of each hide.

The drawings annexed to this specifica' tion show the preferred form of a boarding device according to my invention.

In the drawings- Figure 1 is a longitudinal section,

Fig. 2 is a plan view, and

Fig. 8 is a cross section, on an enlarged scale, of a boarding device according to my lnvention.

Fig.4 is a plan view, on a scale equal to the one adopted in Fig. 3, of the shaft and springs designed to adjust the boarding plate proper.

Figs. 5 to 7 are details of construction.

1 is the top part of the composition boarding plate and :2 is the bottom part or supporting plate. Plate 1 consists of cork or of an other suitable elastic material and should preferably be made in one piece, but in view of its being supported .by the continuous plate 2 it may as well be composed of a number of juxtaposed smaller plates preferably joined together.

The elastic bottom plate 2 is preferably made of a thin wooden. plate built up of a number of thin boards glued up cross-wise and presenting a very great elasticity in all directions. This bottom plate is in its turn supported by a number of laminated springs 3, each spring being composed of three or more flat springs held together by a screw 4: and fastened to a block 5 fixed to a shaft 6 common to all the laminated springs. Shaft 6 is supported near its ends in vertically slotted bearings T fastened to the bottom of a casing 8 surrounding the shaft 6, the springs 3 and the supporting plate 2. Cams 9 fixed on the shaft 6 near its ends and resting against the bottom of the casing and a lever 10 at its free end projecting through the casing outward enable the operator to lift the shaft toward the boarding plates and to control thereby the degree of compression of the springs supporting same as well as the degree of rigidity imparted to said plate. The springs on account of their being fastened to a common shaft can easily be removed from the casing and be replaced by stronger springs if necessary. By providing the lever 10 with a pawl 11 gliding on a toothed segment (not shown) the shaft may be fixed in any position. The free ends of the springs 3 supporting the bottom plate 2 are guided between projections 12 provided on the bottom face of said plate.

The .plates land 2 are prevented from being expelled from the casing :8 by angle irons 13 fastened to the free side edges of said casing, at least one of said angle irons being remoyably fastened in order to :facilita'te the temporary removal of the boarding plate and spring v To this effect screws 14: screwed into the side wall of easing 8 and ,pins 1 5 fastened tothe angle iron are proifided, -the heads of the screws 14 projecting through slots, open at oneend, of the angle iron, while the pins 15 pass through both the casing wall and the angle iron and screwsand pinsalternating with each other.

In order, now, to remove the .angle .iron,

';'the :screws 14 needonly be doosened far enough to allow the :pins 15 to be withdrawn from the perforations provided .in the wall .of the casing. By this arrangementatotal removal :of the screws frequently resulting in :the :loss of :the screws is avoided.

I claim:
